My invention relates to improvements in cop frames, and moreparticularly in the construction of the thread guiding means. The objectof the improvements is to provide thread guiding means which are simplein construction, and in which the reciprocating masses are exceedinglysmall, so that the winding efiiciency is high. With this object in view,my invention consists in mounting the thread guiding means on a rotaryshaft located parallel to the axis of the cop tube, the said threadguiding means comprising a sleeve slidable and non-rotatable on saidshaft and carrying an operating member or members and acting on an armrockingly mounted on said sleeve and carrying the thread guide which isadapted to move in a plane parallel to the axis of the cop frame.

For the purpose of explaining the invention several examples embodyingthe same have been shown in the accompanying drawings in which the sameletters of reference have been used in all the views to indicatecorresponding parts. In said drawings Fig. 1 is an elevation showing thecop supporting means and the thread guiding means,

Fig. 5 is a sectional elevation on an enlarged scale, taken on the line5-5 of Fig. 4,

Fig. 6 is an elevation on a sectional enlarged scale showing theoperating mechanism for the thread guide, the plane of section beingindicated at 6-6, Fig. 4, and

Fig. 7 is a view similar to Fig. 6 and showing a modification.

Referring now to the example shown in Figs. 1

to 3, the cop supporting means and the means for operating the threadguide are mounted in plates 40 and 4 I. The cop supporting meanscomprise a spindle 2 rotatably mounted in the plate 40 and acounterpunch 3 mounted in the plate ii, the said spindle andcounterpunch 3 clamping the cop tube 39 between the same as is known inthe art. The spindle 2 is adapted to be rotated from a friction disk 4through the intermediary of gear wheels 5 and 6. Parallel to the axis ofthe cop tube 39 a shaft l is rotatably mounted in the plates 4|! and M,which shaft is driven from the disk 4 through the intermediary of gearwheels 8 and 9. Further, a screw thread spindle l! is mounted in theplates 40 and 4| which is drige izg from the shaft it through gearwheels 31 an On the shaft 7 a sleeve I2 is mounted which islongitudinally slidable and rotatable in unison with the shaft i, afeather key l3 being provided which engages in a longitudinal groove Idof the shaft 77. The sleeve I2 is made integral with a disk It whichcarries operating members Ii. In the construction shown in the figuresthe said operating members comprise pins 62 having rollers I! mountedthereon. On the sleeve l2 a thread-guide carrier in the form of a blockI5 is loosely mounted which does not take part in the rotary movement ofthe sleeve I 2, a bushing i8 of lubricating material being providedbetween the said parts to reduce friction. The block it is held inposition on the sleeve by means of a split ring 2!] clamped on thesleeve by means of screws I9. The block 65 is provided with a pair ofarms i6. straddling the spindle ii, so that the block i5 does not takepart in the rotary movement of the shaft 7 and the sleeve l2.

The block it is provided with a transverse bore 33 in which a tubularmember 2i is fixed, the said member being held in position by means of ascrew 22 clamping the split top part of the block l5 together. In abushing 23 fitted in the tubular member 2i 2. spindle 24 is rockinglymounted which is held in position within the bushing 23 by means of aring 33 fixed to the inner end thereof. The bushing 23 is fixed withinthe tubular member 2! in a suitable way for example by means of a screw44. At its outer end the spindle 26 is formed with a head to which anarm 25 is secured, which is formed with an angular portion 29 extendinginto position for engagement with the rollers H. To the arm 25 a threadguide 26 is secured which, preferably,

engages in a groove 28 made in the arm 25, the said thread guide and arm25 being held in position on the spindle 24 by means of a nut 21. By theconstruction described the thread guide 26 and the arm 25 may be readilymounted and dismounted. To reduce friction, the bushing 23 consists of amaterial having lubricating property, and the spindle 24 is supported atits inner end on a ball 32.

The arm 25 is formed with a flange 3i disposed goncentrically of the endof the tubular member the and between the said tubular member and flangea spiral spring 30 is located which is fixed with its opposite endsrespectively to the flange and the tubular member, the said springurging the thread guide 26 in one direction and in opposition to theaction of the rollers ll thereon. Thus the thread guide is adapted to bereciprocated by the combined action of the rollers II and the spring 30,

For shifting the thread guiding means longitudinally of the cop tube,the block I is provided with a blade 34 engaging in the screw threads ofthe spindle l1.

The operation of the thread guiding mechanism is as follows:

The spindle 2 is rotated from the disk 4 through the gear wheels 5 and6, and, further, from the said disk rotary movement is transmitted tothe shaft 1 and the screw threaded spindle H. The rotary movement of theshaft 1 is transmitted to the sleeve l2 and the rollers II which act onthe angular portion 29 of the arm 25 and impart reciprocating movementthereto and to the thread guide 26, the return movement of the saidthread guide being effected by the spring 30. The block I5 does not takepart in the rotary movement of the sleeve l2 because it is held inposition by the arms l6 bearing on the spindle ll. As winding continuesthe block l5 and the thread guiding means carried thereby are slowlyshifted longitudinally of the shaft I4 and thecop tube 39. The block l5,mounted as it is upon sleeve l2, carries the sleeve l2 with it in itsadvance upon the shaft.

The shape of the face of the portion 29 of the arm 25 which is engagedby the rollers II is such that uniform movement is imparted to thethread guide, and the thread is uniformly wound into a cop. Preferablythe rollers II are disposed different distances away from the axis ofthe shaft I in such a way that at the outer end of the cop the threadsof the successive layers are deposited one beside the other, the saidthread guide being moved to slightly different end positions. In lieuthereof the rollers ll may be made with different diameters.

In the construction shown in Fig. 3 two rollers ll are provided on thedisk i0. But I wish it to be understood that my invention is not limitedto this construction. In Fig. 6 I have shown a modification in whichthree roll-ers II are provided.

In Fig. 7 I have shown another modification in which the disk I!)carries a cam disk 5| which engages a roller 36 mounted on the arm 25,29.

In Figs. 4 and 5 I have shown another modification. The main parts ofthe mechanism are the same as those described with reference to Figs. 1,2 and 2a, and the same letters of reference have been used to indicatecorresponding parts. However, the mechanism for shifting the block l5longitudinally of the shaft 1 is constructed in a different way. Asshown, the screwthread spindle 52 is non-rotatably mounted in the plates40 and 4|, and on the said spindle an internally screw-threaded disk 35is provided which bears with its outer circumference on the surface ofthe cop being wound. The said disk is rotatably mounted upon an arm 53that extends from block l5 and loosely encircles the spindle 52. Therotation of the cop l is transmitted to the disk 35 which is therebyadvanced on the stationary screw-threaded spindle 52 and carries alongthe block l5.

While in describing the invention reference has been made to particularexamples embodying the same, I wish it to be understood that myinvention is not limited to the general arrangement of the apparatus andthe construction of its parts shown in the figures. For example, I donot limit myself to the construction shown herein in which the cop islocated horizontally. Further, I do not limit myself to the constructionof the mechanism for shifting the thread guiding means.
